WEATHER STREPETG FDR A. HORIZONTAL SASH Gerald D. Peterson, Detroit, Mich. Application May 1, 1953, Serial No. 352,533

4 Claims. (Cl. -69) This invention relates in general to weather stripping and more particularly to a type thereof adapted to provide a seal between the vertical elements of a sash frame and the correspondingly adjacent stiles of a horizontally slidable sash mounted within said frame.

My United States Patent No. 2,663,917, patented Deconditions, could force their way into or through the space i between the vertical sash and frame elements. Thus, the need for means to prevent such entry of snow and moisture became apparent but previously known designs of weather stripping were inapplicable, and no way was apparent to utilize previously known styles of weather stripping without materially and undesirably redesigning the window.

Accordingly, a primary object of this invention is the provision of weather stripping for sealing the space between the vertical elements of a sash frame and the adjacent stiles of a horizontally slidable sash mounted within such frame.

A further object of this invention is the provision of weather stripping, as aforesaid, which can be installed with a minimum change in window structures presently in use and manufacture, and which does not detract from the appearance of the window.

A further object of this invention is the provision of weather stripping, as aforesaid, which is simple in structure, inexpensive to manufacture and can be easily installed or removed by persons unskilled in the construction and/ or assembly of windows.

Other objects and purposes of this invention will become apparent to persons familiar with this type of equipment upon reading the following specification and examining the attached drawing in which:

Figure 1 is a horizontally sectioned view of a sash and sash frame employing the invention.

Figure 2 is a broken, sectional view taken along the line 11-11 of Figure 1.

Figure 3 is an enlarged fragment of Figure 1 in one area of the weather strip.

In carrying out the above mentioned objects, as well as others related thereto, I have utilized a glazing slot in the vertical elements of the sash frame and have provided a similar slot in the sash stiles adjacent to the vertical frame elements. The weather stripping is inserted into one slot of this pair of mutually parallel slots in adjacent vertical sash and frame elements and extends into the other of said pair of slots, thereby covering the space between said sash and frame elements.

For purposes of convenience in description, the terms outer and inner and derivatives thereof, when used herein, will refer to the normal weather side and interior side, respectively, of the window. The terms center and peripheral and derivatives thereof will refer to the geometrical center of the window.

Construction A detailed description of the construction and operation of the general type of window to which this invention is especially applicable has been disclosed in my United States Patent No. 2,663,917, patented December 29, 1953. Therefore, the description herein will be limited to those details of the window structure particularly referred to, and necessary for, a full disclosure of the subject invention.

As shown in Figure 1, the frame 10 is provided with a bottom frame element 11 and a pair of vertical frame elements 12 and 13. The one vertical element 13 may, as shown herein, be a mullion. The vertical element 12 and bottom element 11 have inwardly extending, substantially perpendicular flanges 14 and 15, respectively. The bottom flange 15 has an upstanding rail 16 extending the full length thereof intermediate its inner and outer edges.

The opposed surfaces 8 and 9 of the vertical elements 12 and 13 have opposed, aligned glazing slots 17 and 18, respectively, which extend the full length of said elements and are disposed adjacent to the inner faces 19 and 21, respectively, of said vertical elements. The walls 22 and 23 between the slots 17 and 18 and the faces 19 and 21, respectively, have centerward or opposed edges 24 and 25, respectively, positioned co-planar with said opposed surfaces.

The frame elements may be fabricated from any convenient, conventional material, such as aluminum, and may be secured together as described in said Patent No. 2,663,917.

The sash 30 has a bottom element 31 and a pair of stiles 32 and 33, which in this embodiment, are tubular and have substantially similarly shaped centerward faces. However, the centerward or opposing faces of the vertical elements 32 and 3.3 have grooves 34 and 35, respectively, which "are disposed lengthwise of their elements and adjacent to their outer faces 36 and 37. Said grooves are substantially identical to said slots 17 and 18 both in width and depth. The walls 38 and 39 provided between the grooves 34 and 35 and the faces 36 and 37, respectively, of the elements 32 and 33 have centerward or opposing edges 41 and 42, co-planar with the edges 24 and 25 of the frame elements 12 and 13.

The sash is provided with rollers 43 at its lower corners which support said sash upon said rail 16 for horizontal movement therealong. Pile weather strips 44 are positioned upon the outer faces 36 and 37 of the elements 32 and 33 for engaging the opposing inner faces 19 and 21 of the frame elements 12 and 13, respectively, when the window is in closed position. The sash 30 may be fabricated from conventional materials and assembled in such manner as disclosed in Patent No. 2,663,917.

The weather strip 46 (Figures 1 and 3) is substantially L-shaped in cross-section, having a web 47 and a perpendicularly disposed flange 48 along one edge thereof. Along the other edge of said web47 is head 49 which extends therefrom in substantially the same direction as said flange. The web 47 is of width substantially equal to the distance between the slot 17 and the groove 34, so that, when the flange 48 is inserted into said groove 34 in the corresponding sash stile and the window is in closed position the bead 49 will extend into the slot 17 of a vertical frame element. Likewise, the spacing and dimensions of the parts are such that the bead 49 of the same strip will extend into the groove 35 when the flange 48 is inserted into the slot 18 under similar circumstances.

The weather strip may be fabricated, as by extrusion from any conventional material such as metal, rubber or synthetic plastic, but it is preferably of resilient, moldable, material such as one of the vinyl compounds. It is preferably in one piece (Figure 2) extending from the top to the bottom of the window.

Operation The installation of the weather strips 41: and the operation of the sash equipped with such strips is probably obvious from the foregoing description.

When the sash 30 is in closed position (Figure 1), the edges 24 and 41 are coextensive centerwardly as are the edges 25 and 42. The flange 43 of a weather strip 46 is inserted into the groove 34 in the sash stile 32. The web 49 thus extends across the edges 24 and 41 and the bead 49 extends into the slot 17.

In a similar, but reversed, manner the flange of a strip 46 is inserted into the slot 18 of the mullion 13 so that the bead 4? extends into the groove 35 and the web 47 extends across the edges 25 and 42. Accordingly, the sash 30 can be moved freely out of the closed position along the rail 16 without any interference whatsoever from the weather strips 46. In such movement, the weather strip mounted upon the sash stile 32 moves with the sash away from the frame element 12, and. the stile 33 moves away from the weather strip mounted upon the mullion 13.

The particular shape of the strip 46 and the parts of the window with which it is used permits it to be used. in both of the positions indicated in the respective upper and lower parts of Figure 1 without modification. It is required only to reverse a length of strip end-for-end with respect to its position in and with the slot 17 and the groove 34 to insert it into the slot 18 and groove 35, or vice versa. This is obviously advantageous in that it requires only one design of strip to function effectively in both places of use.

The weather strips may be installed for seasonal removal, or permanently installed by appropriately cementing their flanges 48 into their respective grooves or slots.

Although a preferred embodiment of my invention has been disclosed hereinabove for illustrative purposes, it will be understood thatmoditications thereof will lie within the scope of this disclosure unless the appended claims specifically state to the contrary.
